Biography
Helmut was born in what is now Moravia in the Czech Republic to the Germanic Quadi tribe, and he became their king during the 3rd century AD. In 270 AD, he took advantage of the Roman Empire's internal strife by invading its Danube frontier provinces, conquering their city of Aquincum in Pannonia. This came at the same time as the Buri invasion, which almost cost Rome all of its northeastern border provinces. However, the Roman Army dispatched several legions to deal with the Germanic threat.
